The new surgical tool inspired by a wasp


Scientists in the Netherlands have mimicked the way parasitoid wasps lay eggs to design a new tool for keyhole surgery. Currently tools used in these procedures are prone to clogging because they use suction. The new device avoids this by using friction.

The team, at Delft University of Technology, have a working prototype and hope the tool will be ready within a few years.
